Find the rate of change of total revenue, cost, and profit with respect to time. assume that r(x) and c(x) are in dollars. r(x)equals60 x minus 0.5 x squared, c(x)equals2 x plus 5, when xequals35 and dx divided by dtequals20 units per day

d≈7.07in

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
